Title: Method and apparatus for decoding error correction code
IPC: H03M/
Filed: 1984-12-19
Abstract: An apparatus for decoding non-dualistic error 
correction codes in which a syndrome is a result of an 
addition of a series of received symbols in (mod.2) and by 
which the error of a plurality of symbols in said series of 
received symbols can be corrected, which comprises a 
syndrome register for storing said syndromes so that an 
error value with respect to a symbol can be formed by 
subtracting another error value from a value stored in said 
syndrome register in connection with a plurality of 
erroneous symbols. This is usable with a method for 
decoding Reed-Solomon code which can be solved by erasure 
correction in accordance with the expression: 
  
where, ν = 0 to d - 2  
n : Number of erasure  
X k  : Location of kth  
S ν  : Syndrome  
Y k  : Magnitude of error in the erasure of kth  
d : Minimum distance of code

Title: Process for amelioration of the precision of dosing of a controlled balance for differential dosing
IPC: G05B13/04
Filed: 1990-07-14
Abstract: In a process and an apparatus for improving the metering accuracy of a differential metering balance connected to a controller and to an estimator, there is an evaluation device which minimises at least two stochastic disturbance variables by means of a model computation. For this, the evaluation device contains an analyser circuit which scans an estimated-value signal for a specific period of time and which forms the power-density spectrum of this. Those frequencies which exceed the value of an especially high power density are determined from the power-density spectrum in an identifying circuit. These frequencies serve, in a correcting circuit to form a frequency spectrum which corresponds to the actual stochastic disturbances. In a comparator circuit, this spectrum is compared with a model spectrum calculated by a model-computing circuit, and that model coming nearest to the actual spectrum is determined. A controller-setting circuit then determines from the model spectrum obtained the spectrum which corresponds to that of the pick-up disturbances and of the bulk-density disturbances. The controller-setting circuit forms from this a signal which serves for optimising the controller.

Title: Heaterless adsorption system for combined purification and fractionation of air
IPC: B01D53/047
Filed: 1990-04-05
Abstract: A process for the sequential purification and 
fractionation of air in a single column and in the 
absence of pretreating the air feed to remove moisture 
comprises passing an air feed containing a gaseous 
component harmful to humans through an adsorber column 
(13,25) to produce product effluent. The column has at 
least two adsorption zones (14,26;15,27). The first zone 
(14,26) comprises a feed purification adsorber for 
purifying an air feed and having a first adsorbent 
therein for adsorbing the harmful gaseous component and 
water vapor from said feed to effect purification. The 
first adsorbent is capable of being regenerated. The 
second zone (15,27) comprises an air fractionation 
adsorber for adsorbing at least one component of air and 
having a second adsorbent therein to effect fractionation 
of air. The second adsorbent is capable of being 
regenerated. The first zone operates as a heaterless 
 
 
pressure-swing adsorber and said second zone operates as 
a purge sweep adsorber. The column (13,25) is sized so 
that the heat of adsorption released during the 
adsorption of water vapor from the air feed is retained 
in said column and so that on application of a volume of 
purge gas to said column said first and second adsorbents 
are both regenerated. The second zone (15,27) is sized 
so as to contain sufficient adsorbent to carry out the 
fractionation unaffected by the heat front generated by 
the heat of adsorption released in the first zone and to 
prevent breakthrough of the mass transfer front during 
fractionation. The product effluent is removed from said 
column.

Patent EP-0554810-A3 (EP)
Title: Electrical connector
Inventor: HARTING DIETMAR
IPC: H01R12/08
Filed: 1993-01-30
Abstract: For an electrical connector for connecting insulated electrical conductors, preferably an electrical plug and socket connector, with contact elements disposed in chambers of a carrying base with cutting and insulation displacement connections for connection to the conductor, the conductors being introduced into the connector in the axial direction, relative to the contact elements, it is proposed that the conductors be pressed by means of a conductor guiding element, which is constructed as a pressure part, into the cutting and insulation displacement connections. At the same time, the conductors are pushed through a guiding borehole, in which they are deflected in such a manner, that they are guided obliquely through a recess in the conductor guiding element. When the carrying base and the conductor guiding element are joined together, the cutting and insulation displacement connections dip into these recesses and, in so doing, are connected with the conductors.

Title: Process and device for adaptive digital cancellation of the echo generated in non-stationary telephone connections
Inventor: CANNALIRE GIACOMO
IPC: H04B3/23
Filed: 1993-02-12
Abstract: An echo cancellation device usable in telephone connections affected by phase-roll is described. The canceller calculates the echo path propagation delay and produces an estimate of the echo signal by digitally filtering the signal originated by the far-end talker. The echo estimate is then subtracted from the actual echo to eliminate listening disturbances therefrom. The filter used is of the FIR type with adaptive coefficients updated iteratively by adding algebraically, to the values which they had upon the preceding iteration, a correction term proportional to the estimate error. The frequency of the coefficient updating iterations is a multiple of the rate fc of acquisition of the voice and echo samples by the canceller. <IMAGE>

Title: Intraluminal manipulator.
Inventor: ORTIZ MARK
IPC: A61B19/00
Filed: 1993-11-18
Abstract: The present invention is directed towards an intraluminal manipulator which extends into a lumen and is operable to position and manipulate the tissue surrounding the lumen as necessary during a medical procedure. The manipulator includes a head, a handle and an interconnecting shaft. A pair of cables extend through the shaft and interconnect the head and handle. Movement of a trigger provided by the handle moves the head, which is formed by a series of articulated links, between generally straight and arched configurations. Movement of the trigger in one direction moves the head from a straightened to an arched configuration, while movement in an opposite direction moves the head from the arched to the straightened configuration. When placed in the straight configuration, the head is insertable into and removable from the lumen. When the head is in the arched configuration, it engages the walls surrounding and defining the lumen and can thereafter be used to manipulate the tissue. A fiber optic bundle is provided to allow remote visualization of the lumen, and an expandable balloon is used to provide a better frictional engagement between the head and the tissue defining the lumen.

Filed: 1994-10-10
Abstract: A scrambling system has a scrambling apparatus
and a descrambling apparatus for scrambling and
descrambling a digital audio signal having a plurality of
16-bit long sample data units. The scrambling apparatus
(12) has a detector (221) for detecting, in each sample
data unit, a meaningless portion which is a portion
including the MSB and a meaningful portion which is a
portion including the LSB, and applying scrambling only
to the meaningful portion. Since the meaningless portion
is not scrambled, no error data will appear in the
meaningless portion. Thus, an unexpected abrupt change
in sound caused by a bit error in the meaningless portion
which has bits with greater weighted value can be
avoided.
